Keni, its time to drop Vsampler and goto Kontakt. You wont loose anything because Kontakt can import Vsampler samples and its programs. 
 
Heck Kontakt can read just about any sample format. 

John gives great advice on this Keni.  Kontakt is amazing. I would be surprised if it didn't  make a huge difference to your system stability to have all 64bit plugins. A few people seem to get lucky running old 32bit plugins,  but most don't.  You should not have to worry about blue circles and waiting 30 sec. What a buzzkill:)
